7. Warning Features
When this watch becomes undercharged, a warning feature is activated and the display
of the watch changes.
2-second interval
movement
<Insufficient Charging Warning Feature>
When the second hand is moving in 2 second intervals (moving once every 2 seconds),
this means that the watch is undercharged. Although the watch will continue to run
normally at this time, the watch will stop if 2-second interval movement is allowed to
continue for roughly 1 day. When this happens, charge the watch by referring to Sec-
tion 6 entitled, “Charging Procedure” so that it returns to normal 1-second interval
movement. Furthermore, the chronograph function cannot be
used when the insufficient charging warning feature has been
activated (during 2-second interval movement).
* If charging is only performed until the watch returns to 1-sec-
ond interval movement, it will again return to 2-second inter-
val movement within a few minutes. It is therefore recom-
mended to additionally charge the watch for at least one day’s
worth of charging by exposing to light or by swinging (200-
300 times) to ensure continuous operation.

* Charging will not proceed efficiently if the watch is swung too fast or too slow.
* When swinging the watch, although the sound of the generator turning can be
heard from inside, this is normal and does not indicate a malfunction.
* The watch should be swung approximately 200-300 times to ensure 1 full day’s
worth of charging when running normally (1-second interval movement).
* Charging can be performed even more efficiently by combining charging by ex-
posing the watch to light and charging by swinging.
* Since this watch is provided with an overcharging prevention feature, there is no
risk of damage to the watch due to excess charging.
